2. Grid Reference
  • A grid reference is a 6 digit number
  • The grid reference will tell you the exact location of a point or place
  • It is calculated by dividing the area reference box into 10 sections
  • You add another number to the end of the 2, 2 number sections
    • eg. In the above picture, the top point of the triangle would be at 255668
  • Objects that lye on the line (the star in the middle) would be at 250650
